TS 808 mod problem or not?

TS 808 mod problem or not?I changed the opamp to a regular RC4558, which sounded okay. Most importantly I put a socket in there for future mods... The problem I have now is there seems to be a bit of distortion coming through when in bypass mod. Does this have anything to do with the two resistors that were changed on the output jack? I don't think I am imagining it can't hear the distortion when the pedal is out of the loop.

in removing the op amp I might have over heated somethings. I didn't use the clip lead method to removed the chip. I used the lazy ass sloppy method which consists of pushing the leads out with the soldering iron... Would the heat be enough to transfer along the buses? Are the other components that sensitive? Man, The leakage isn't a lot but I think it'll bug me!
